ToyTec Ultimate and a lot of weight in the bed

I've got the ToyTec Ultimate lift and after a few more mods i will have a good amount of permanant weight in the bed. My topper has got to be 200ish lbs and the bed/drawer system i am building is going to be almost the same is my best guess. Should I be getting a heavier duty add a leaf for the back? What are my options?

We do offer a Heavier Duty AAL, but honestly, in your situation, you would be better off replacing that leaf pack with a custom one, that way you can dial in your exact ride height you want, as well as the weight capacity needs you have.
